D8 Integration and Experimentation
  • D8 is an output of WP 4 This WP will integrate
    the HW/SW developed () Qualitative study of the
    social and anthropological consequences of the
    utilization of the system.
  • T4 .1 Small Area Scale Integration Integrate
    part of the HW/SW developed (reduced networking
    and services capabilities), and install it in
    each node in a small and test this system in
    order to identify HW or simple networking
    problems and integration errors. Fix
    problems/errors found verifying that the system
    operates correctly. (input to D8 - month 22 (July
    2004) All
  • T4 .2 Small Area Scale Validation and Analysis
    Validate the small scale MobileMAN from a
    technical (i.e., the technical constraints and
    limitations of the system), and social
    standpoint. The latter will be performed by
    measuring the acceptance -- from Virtual
    Communities (VCs) of users -- of the MobileMAN
    system when running some simple application(s).
    This will task will also monitor the social
    construction and human behaviour of the VCs.
    (input to D8 - month 22), (D17 - month 34 ) All

D11 MobileMAN functionalities enhanced set
  • D11 HUT is responsible for this deliverable
    (month 25)
  • D11 is an output of WP 3
  • T3.2 Implementation of Location Protocols
    Develop new location and discovery protocols
    based on the nearness metric. Implementation of
    it for the Linux operating system. (input to D6,
    D11, D14)
  • Service discovery embeeded in the routing
    protocol instead of users location
  • T3.3 Routing and forwarding Develop routing and
    forwarding protocols for the self-organised and
    co-operative communications of MobileMAN.
    Implementation of them for the Linux operating
    system, in co-operation with the task on security
    (T3.4). (input to D6, D11, D14)

D11 MobileMAN functionalities enhanced set
  • T3.4 Security and Co-operation Model
    Implementation of the collaborative reputation
    mechanism (CORE) proposed to solve ad hoc node
    misbehaviour. Implementation of the CORE
    mechanism for the Linux operating system, in
    co-operation with the task dedicated to the
    definition and implementation of the routing
    algorithm adopted by MobileMAN (T3.3). (input to
    D11, D14)
  • T3.5 P2P delivery mechanisms Implementation of
    the P2P mechanisms designed in Task T2.6. (input
    to D11, D14)
  • T3.6 Risk reduction in the system development
    This task will be activated, if required, by the
    self assessment procedure to tackle the risks
    emerging during the implementation of the system
    solutions. The objective of this task is the
    identification of alternative solutions for
    implementing the system solutions when adopted
    approaches are too complex and risky. (input to
    D11, D12, D14

D8 (and D11) Actions
  • Proposal An experimental trial to be setup in
    Pisa involving junior researchers from all
    partners
  • This group of people should have continuous
    exchanges via e-mails, chat, etc, and meet
    regularly (from now to the end of the project) to
    verify the status of software implementation and
    integration
  • Why?
  • Construct a small MobileMAN (D8) now and to work
    toward a larger testbed
  • To address software integration, fix problems in
    existing software, better coordinate ongoing
    software development activities etc.. (D8 D11)

WP 4
Description of work Given the high challenges of
this WP, the main tasks to be performed in it
(integration and acceptance) will be addressed at
two different area scales campus-wide area scale
(T4 .2 and T4 .3) and large area scale (T4 .4 and
T4 .5). T4 .1 Small Area Scale Integration
Integrate part of the HW/SW developed (reduced
networking and services capabilities), and
install it in each node in a small and test this
system in order to identify HW or simple
networking problems and integration errors. Fix
problems/errors found verifying that the system
operates correctly. (input to D8 - month 22)
All T4 .2 Small Area Scale Validation and
Analysis Validate the small scale MobileMAN from
a technical (i.e., the technical constraints and
limitations of the system), and social
standpoint. The latter will be performed by
measuring the acceptance -- from Virtual
Communities (VCs) of users -- of the MobileMAN
system when running some simple application(s).
This will task will also monitor the social
construction and human behaviour of the VCs.
(input to D8 - month 22), (D17 - month 34 )

II Year Activities
  • The objectives reported below are the detailed
    criteria for evaluating the success of the second
    year of the project.
  • MobileMAN architecture implementation (CNR)
  • - Implementation and validation of the MobileMAN
    architecture as defined during the first year
    (see D5) considering both the original and the
    new reference model.
  • New applications and services (Netikos)
  • Adaptation of existing applications (or classes
    of applications) identified, during the first
    year, as ones that can become a customer
    advantage, when run on top of MobileMAN, compared
    to traditional technologies.
  • Middleware (Cambridge)
  • - Adaptation of Pastry middleware for the
    MobileMAN environment to exploit cross layering.
  • - Development of new solutions for P2P
    information delivery based on Pastry.
  • Co-operation Model (Eurecom)
  • - Implementation and validation of the
    cooperation models and mechanisms defined during
    the first year.

26
II Year Activities (cont.)
Networking services (CNR, HUT) - Include the
cross-layering view at network/transport
layer - Design of packet forwarding schemes
suitable for MobileMAN. - Implementation and
validation of location scheme defined during the
first year. - Development and testing of a
complete ad hoc network Wireless Technologies
(SUPSI - DIE) - Include the cross-layering view
at datalink layer. - Design and implement a full
datalink layer that includes the enhanced MAC
protocol for ad hoc networks as designed during
the first year. Socio-economic Model (SUPSI -
DLS) - Apply the developed methodology for
evaluating social, anthropological, and economic
potential of MobileMAN, and provide the results
for improving the technical parts.
27
II Year Success Criteria
The goals for evaluating the success of the
second year of the project are - The software
implementation of the solutions defined and
studied during the first year, except the
MobileMAN enhanced NIC. - The integration of the
developed solutions in a fully functioning
testbed. - Preliminary measures of the users
satisfaction of the ad hoc networking paradigm.
These measures will be mainly done by empirical
research based on forms to be filled. In
addition, some measurements with a small group of
users (on a simplified testbed) will be also
performed. - To investigate market-based
mechanisms for exploiting the self-organised
paradigm. This will take into account both the
users satisfaction and the advantages provided
by the MobileMAN environment to some class of
applications.
